Tracy,
Let the 1st angle = a, the 2nd angle = , and the 3rd angle = c. Then angle a = 3b and angle c = 2b.
We also know that for any triangle a + b + c = 180°
So substituting a = 3b and c = 2b give: 3b + b + 2b = 180°, so 6b = 180°, which means b = 30°.
If a = 3b, then a = 90° and c = 2b means c = 60°. so we have a right triangle with sides of 90°, 60°, and 30°.
